The application of small-diameter seamless steel pipe has been applied in many areas, mainly in the metal industry, building materials industry and some construction pipeline industries. However, the production of small-diameter seamless steel pipe should follow certain technology. The process flow of processing technology is very important, so conventional technology cannot be less. Let's mainly take a look at the production process flow of small-diameter seamless steel pipe.
The production process of small-diameter seamless steel pipe mainly includes cold drawing, hot rolling and hot expansion. The main processing procedures include blank sawing process, ring furnace heating process, perforation process, pipe rolling process, sizing process, cooling bed process, straightening process, pipe cutting and soot blowing process, magnetic flux leakage flaw detection process, surface inspection and length measurement, weighing to packaging and warehousing.
The main technical standards include seamless steel pipe for structure GB / t8162-2008, seamless steel pipe for fluid transmission GB / t8163-2008, seamless steel pipe for low and medium pressure boiler gb3087-2008, hot rolled seamless steel pipe for hydraulic prop GB / t1396-1998, seamless steel pipe for high pressure boiler GB5310-2008, API casing and oil pipe specification api5ct, pipeline steel pipe specification api5l-44, and seamless steel pipe for low temperature pipeline GB / t18984-2003.
